“Meanwhile in the 13th century the most celebrated of early Thai states was
the kingdom of Sukhothai. Modern Thais regard Sukhothai
as the birthplace of the Thai nation, particularly under Ramkhamhaeng, king
c.1279 – 1298, whose rule is celebrated by the Sukhothai stone – an inscribed
obelisk reputedly discovered in 1833 by the Thai prince Mongkut, then a monk
and scholar and later Thailand’s first modernising monarch. The inscription
portrays Sukhothai as an idyllic place, governed by a just, fatherly and
devoutly Buddhist monarch. Possibly it is Ramkhamhaeng’s self-justifying
counterblast to the arrogance and avariciousness of imperial Angkor.
In recent years the stone’s authenticity has been questioned, some sceptics
arguing that Mongkut himself devised the inscription to give his people an
appealing early history”.History of South Asia, Asean Focus group.

“During the reign of the Vietnamese king, Minh MÕng, the Champs were severly
persecuted. As a consequence, the last Champa Muslim king, Pô Chan, decided to
gather his people (those on the mainland) and migrated south to Cambodia.
Whereas those on the coastline, they migrated to Trengganu (Malaysia). The
area where the king and the mainlanders settled is still known to this day as
Kompong Cham. They were not concentrated in one area but were scattered along
the Mekong river in Vietnam,
forming 13 villages along it. Throughout the years, their children were sent to
Kelantan (Malaysia)
to learn Qur’an and Islamic studies. Once studies were completed, these
children then return home to teach others in these 13 villages”. http://www.angelfire.com/vt/vietnamesemuslims/hstry.html
